187586 ÷ 12 
Our goal is to divide 187586 by 12.

On to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 12

Let's proceed to step 2:
When dividing 18 by 12, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 12 from 18 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

Step 3:
12 can be fit into 67 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 60 from 67, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 12

Step 4:
When dividing 75 by 12, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we subtract 72 from 75, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 12

Advancing to step 5:
The number 12 fits into 38 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1563.0
Subtracting 36 from 38 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

Step 6:
When dividing 26 by 12, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 15632.0
Subtracting 24 from 26 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
12 goes into 20 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 15632.1
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 15632.16
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 15632.166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 15632.166 with a remainder of 0.0008.
